Script works in Solo but not Multiplayer, why?

so I made this script and it works in solo but not multiplayer

does anyone have a few fixes?

ps: its a regular script in Workspace

--define vars
local Players = game:GetService("Players")
local maps = game.ServerStorage:GetChildren()
local inprogress = false

--initiate round
while wait(1) do
    if inprogress == false then
        inprogress = true
        for _,player in pairs(Players:GetPlayers()) do
            local Hint = game.ReplicatedStorage:WaitForChild("HintMessage"):Clone()
            Hint.Parent = player.PlayerGui
            Hint.TextHint.Text = "Intermission"
            local randmap = math.random(1, #maps)
            local MapClone = maps[randmap]:Clone()
            wait(4)
            Hint.TextHint.Text = "A map has been chosen!"
            wait(2)
            Hint.TextHint.Text = "Selected map: " .. maps[randmap].Name .. " Map!"
            wait(2)
            Hint.TextHint.Text = "Fight!"
            MapClone.Parent = game.Workspace
            wait(0.5)
            game.Workspace.SpawnLocation.CanCollide = false
            game.Workspace.SpawnLocation.Transparency = 0.4
            wait(5)
            for t = 120, 1, -1 do
                Hint.TextHint.Text = "Time left: " .. t
                wait(1)
            end
            Hint.TextHint.Text = "Game over!"
            wait(3)
            game.Workspace.SpawnLocation.CanCollide = true
            game.Workspace.SpawnLocation.Transparency = 0
            MapClone:Destroy()
            Hint:Destroy()
            inprogress = false
        end
    end
end
